Hypobaric Altitude Simulation Methodology
To get high-altitude validation spot on, we entirely bypass standard, run-of-the-mill vacuum rigs. When you are testing electric vehicle batteries or heavy-duty aviation components, you rely on true physical pressure reduction.
This hypobaric approach is widely recognized as the industry benchmark for helping you meet strict compliance standards like MIL-STD-810H, NASA-STD-5001, and RTCA DO-160. We use heavy-duty vacuum pumps to physically draw the air out of the thick steel enclosure until the internal pressure drops to a near-vacuum of 0.5 kPa (500 Pa).
It is the most reliable way to verify if your product's outer shell will swell or warp under pressure. Whether you use our highly compact 250-liter QualiATC-250 or the massive, high-capacity 2000-liter QualiATC-2000, it effortlessly mimics thin-air conditions at five thousand, eight thousand, or even an extreme forty thousand meters above sea level.
Core Environmental Variables & Chamber Control
Maintaining a highly stable environment inside an Altitude Test Chamber is a severe technical challenge unless you have exceptionally smart control systems running the show. We pack these testing enclosures with high-performance hardware to control every single variable:
Precision Vacuum & Pressure Control
To mimic an aircraft dropping swiftly or climbing into the clouds, the machine uses highly responsive electronic expansion valves (like the Danfoss AKV) and heavy-duty mechanical pumps. It can transition the internal pressure all the way down to 0.5 kPa in just a matter of seconds.
Broad-Range Temperature & Humidity Regulation
Up high, it’s not just the oxygen-starved air that threatens your electronics; it's the freezing cold temperatures. Our internal refrigeration setups use specialized VRF (variable refrigerant flow) technology paired with hot gas defrosting to entirely prevent frustrating ice buildup. This lets the machine swing from a freezing -70℃ up to a blistering +180℃, all while maintaining internal moisture levels anywhere between 20% and 98% RH.
Siemens PLC Controls & Remote Monitoring
To prevent the climate environment from drifting during a long, multi-day test run, the internal system uses a top-tier Siemens control platform. It instantly corrects any tiny mechanical hiccups so your compliance test stays completely on track. Plus, thanks to our integrated EZNET remote technology, you can actually keep a close eye on your ongoing test data directly from your smartphone or office laptop.
High-Precision Sensor Calibration
We constantly double-check the built-in measurement tools using highly certified reference gases. There is absolutely zero room for loose or drifted measurements here; every single internal sensor must be shockingly accurate to ensure your test results are completely authentic.
